Child Protective Services investigating death of a Yonkers toddler

The death of a Yonkers toddler draws questions about how she ended up back in her mother's care.

Uniqua Smith, 20, is charged with second-degree murder in the death of her 2-year-old daughter Theresa. Police say Smith beat Theresa to death for wetting her pants.

According to Nancy Travers, Westchester County's deputy social service commissioner, the child was only returned to Smith's care in June after she finished rehab for a drug problem.

Travers says Smith lost her daughter last fall after leaving Theresa with a stranger and disappearing. After finishing a drug rehab program, Theresa was placed back in her mother's care. Travers says follow-up visits uncovered no signs of abuse.

But now, Theresa's death is the focus of a state and local investigation by Child Protective Services.
